GARBAGE-INCINERATOR. Y A

To all u'lwm it -imry concern:

Bc itliiiown that I, "iLLLm ll. VAN Donnx, a citizen of the United States, residiupr at Los Angelefn' in the county ot' 4Los Angeles and Stato of California, have invented ai new and useful Garbage]neineratur, of which the following isa specification.

This` invention relates to nic-.ans for disposing-of garbage andv the like by burning the saine. I

It is of the objects of this invention to provide ready p burning garbage in nu economical and eil`eetive manner; t-o provide a comparatively cheap plant for accomplishing the above object; to consume the gases and ellluvir and reduce the f rarbage to ashes in great quanti- Irefetzibly the incinerador -ber (ir-Lunnel, und nie' ties and with great .re pidity.

This invention is pioneer iii that meansv are provided whereby the garbage put into motion along in upwardl \v inclined chaniber immediately it enters the incinerator, und at the saine t-inie is subjecte-il to the 'lire from oil or gas burners, and die :Neending inotion of tlic garbageand the api i1. ation of the fire and the motion of the garbage is made emitiniious` throughout the apparatus from the time the material enters the iueineriitor until all the combustible material, except the liquidsl hat may HoW'uwAy, consumed. Instead of iiist drviiigtlie material iuaniiicliiied way and then delivc-iiigr the sa inc t afurnaee.

of combustion for e. considerable linie to the top of the inclined way, thereby becoming incinerated to n great extent and t-lioroughlv lieated after which the material is further acted upon by i'ire' in a torruozis eliirnnev.

G is an Aapron Aeon'v'egfer moved by a, s )rocket cliaiii 7, and sprocket wheels S, 9, 't ie driving wheel S being located at the bottoni of the slaiiiiiiitr tuniiei 4, and the other wheel 0 bein;r located at 'the junction of .said tunnel lwith the passage of the chimney, so that the eonveyer is curved aud surrounded b v the tunnel. thereby mal-:ing a conduit for the mi age of heat from the touibustion of fluidI fuel around over and in contact with 4 is a. drying nud burning ciiainher in theI the refuse carried up through the tunnel by n the eoii\'e vei. The driving sprocket wheel S will he propelled by nii engine, not shown, lo carry the garbage u iwarll in the direction of the arrow from the bottoni to the top of said slantiiilgr chamber.

11 designates fluid fuel burners arranged at various points in the drvwng and burning tunnel to npplv tire to the material to beV v figure .l is a sectional elevation oi the iul if', 2 is a view oi the iucineiatoi 1 dried and burned. 'lliese burners ma)- he applied in any suitable wavand iiiav be ariin ranged to produce any desired lient in the tion of the drying and burning glianiber. i drying and burning conduit.J so thatas the stack. Thiit is to say, below the inlet thereinto from the' convjeyer. As indicating said furnace, 12 designates lliiid fuel burners for producing fire at the bese oi' the stack andA whenever desired in the chimney. These may be arranged t any desirable place from vbottoni to top of the chimney to till the chimney with fire if necessary lo incinernte the materiel dumped from the conduit into the chimney through the hole i3 at the top of the drying and burning tiinnei 4.

14 designates `:in ash-pit :it the bottom of the chimney.

In practical operation the conveyer will be driven continuously and the garbage or other material to be inciiierated will be dumped on to the lower end ot' :ne apron rind will thereby be ,carried upward alongl the chamber and dumped over into the chimney. The ufire from the several oil burners attacks the moving mass, rapidly drying the same and burning the gases and eiliuvin which eniiinate from the' garbage. -is the garbage burns, the ashes are carried up by the api-on and dumped along with the iznbuiiied inaterial into the chiinn'e down which it with the uiiburiied materia descends and finally reaches its resting lace in 'ihe ash-pit..

The drying and urning chamber is pref einbly oval in cross-section in order to give most effective deflection and reverberation of the heat.

As the unburned material drops down the chimney, the fire in said chimney acts upon the saine to consume it. The sslies may be removed from tlieash-pit` by any suitable means, and the garbage or othar material to be iiicineratcd may be fed int-:- he. inlet 10 by a. conveyor 15 or any other means desired orf convenient.

The return liin'b of the npr-iii und its sprocket chains may be in the opt-n nir or in a drai'tdlue, as :it 16, in order` to prevent the saine from becoming too highly heated.

It will thus be seen that lby means of this invention the combustion of the garbage begins immediately after the seme has entered the furnace, :ind the combustible gases begin to arise therefrom under the direct action of the lire, and at the same time any liquids may flow down the lloor of the slant ing chamber, and that` as the garbage ascends it becomes more combustible owing to theV escape of the inoist-iire therefrom und the accumulation of lient therein, so that by making the ascending chamber of suitable length, the materiel maybe largely consumed in the chamber, and the. unconsuined garbage may be brought to the point of ignition before being discharged into the tbrtiious passage of the chimney.

l do notcliinit myself to the dimensions hereinbefore stated, but such stated dimensions will ali'oi'd an incincrator of large capacity. A

The burners l2 in the cliimne are prefer- 1. An incineriitor comprising u stack, an

upwardly inclined conduit to. ojpen into the.

stack, an upwardly inclined conveyor in the conduitl to-discharge ,into the slack, n iluid fuel burner at the ase of the conveyor, and a furnace at the base of the stuck to complete the combustion of unbiirned combustibles thtis discharged. i

2. An incinciiitor comprising ii. stack, an upwardly inclined conduit opening into the stuck, an upwardly inclined conveyor in the conduit to' discharge into the st-ack, orie or more fluid fuel burners to direct a. lire blast along the conduit and a furnace to receive end consume combustibles that nin)Y be discharged into the stack.

In testimony whereof, I have hereunto set my hond nt Los Angeles California this 5th day of September v1906.
